Daihatsu Rocky

Hi one and all got a dooza for yous and dont rag me to much about the rocky cause it aint mine just a mates . The Daihatsu Rocky 2.8 deisel engine is buggerd and the price of another is just not practical as it is just a runabout would anyone know whether a 2.8 petrol would bolt straight in or is there a fair bit of buggerising around to get it in it is a 1988 modle and still not to bad for its age. cheers for all the replies that I hope I will get and just one thing that I got off the news in WA tonight there is a few shires over here that are going to trial 30 Ks an hour past schools and 40Ks an hour on the streets , it will be faster to walk down the shops than drive .
